About this study
Safety and efficacy of ADR-001 are evaluated in Patients with Severe Pneumonia caused by SARS-CoV-2 infection.
Read the detailed description
Patients with Severe Pneumonia caused by SARS-CoV-2 infection are enrolled to the study. Adipose-derived mesenchymal stem cells (AD-MSCs) are administered once a week, total four times intravenously. Safety and efficacy of AD-MSCs are evaluated for 12 weeks after first administer.
- Being tested
- Mesenchymal stem cell
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mesenchymal stem cellBiological
1*10^8 cells are administered once a week, total four times intravenously.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Mesenchymal stem cell in people with Severe Acute Respiratory Syndrome Coronavirus 2, run by Rohto Pharmaceutical Co., Ltd. at 1 site in Japan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety: Adverse Event (time frame: 12 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Dec 2024; AzTrials last refreshed its copy on 6 Nov 2026.
